Trilla, IL population, income and ZIP codes

Trilla CDP is a very small community in Illinois, with 118 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1319 of 1,462 ranked by population — larger than 9% of them. The median age here is 26.5 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in Trilla CDP earn a median of $120,625 a year, 53.6% above the national figure of $78,538 and 62% above the $74,244 median for the 698 Illinois cities we cover. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 0% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Trilla CDP is valued at $96,100, 68.3% below the national figure and 46% below the $179,100 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 0.8×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 100% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

A median age of 26.5 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address. With 118 residents, a handful of survey responses moves every median on this page. Compare Trilla CDP against its county rather than against national figures.

The Census withheld gross rent for Trilla CDP because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.
